Primary Examiner-Wilbert J. Briggs, Sr. Attorney, Agent, or FirmLawrence S. Pope [5 7] ABSTRACT Polycarbonates based on aromatic bishydroxy compounds which contain s-triazines of the formula R where:

R has the same meaning as R, and is identical or not identical with R and can be linked to R? via alkylene radicals with 2 to 5 carbon atoms which can be interrupted by hetero-atoms, such as O, and NR, that is R R can be alkylene with 2 to 5 carbon atoms which can be interrupted by 0,8 and NR, with the proviso that the rings formed by R, Z and R are from threeto six-membered rings; and wherein R is an alkyl radical with lto. 4 carbon atoms, a phenyl radical or an alkylaryl radical with a total of up to l carbon atoms, 7 I or R and R can be aryl linked-,vja a single bond or O or S, as linkages between the aromatic bis-hydroxy compounds and bonded to oxygen-atoms-of the latter.

The new high molecular .polycarbonates areessentially built up of identical. or' non-identical structural units of the following general forinula la' in which Z, R, R and R have the same meaning as indicated under formula 1 and n is a number between 1 and lOO, preferably between 1 and 20,

X denotes an 0-, mor p-phenylene radical, an 0-, mor p-phenylene radical with one or more substitutents, possible substitutents being, for example, lower alkyl groups with l to 4 carbon atoms, or halogen atoms, among these especially chlorine or bromine, or denotes a radical characterized by the formula 2 II ll SO2 or a radical of the formula 33. or 3b I l I C I I R4 R4 R4 3a 3b wherein I R to R denote alkyl radicals with l to 5 carbon atoms, but

R can also represent halogen atoms, for example chlorine or bromine; Y I

The average molecular weight M of the polycarbonates according to the invention is generally above 10,000, preferably between 20,000 and 200,000. However, it is also possible without difficulty, to manufacture polycarbonates, containing s-triazine rings, of lower molecular weights.

The end groups of the new'polycarbonates have no decisive influence on the properties of the products. For the sake of completeness, the following may be mentioned as end groups A for the left-hand side of the above structural formula, and as end groups B for the right-hand side:

R-ZYNWI/Z-R wherein R is a phenyl radical or a phenyl radical with one or more substituents, and

Z and R have the abovementioned meaning;

B represents OR wherein R has the abovementioned meaning.

As a result of the incorporation of the s-triazine structural units, the new high molecular polycarbonates according to the invention have a raised glass transition temperature and increased stability to saponification, and also improved burning behavior relative to comparable polycarbonates which do not contain any co-condensed s-triazine structural units. These effects were not foreseeable.

In contrast to the polycarbonate, described in SU-PS No. 240,233, based on the bis-hydroxy compound with a reactive chlorine atom in the s-triazine system A represents H,

which can furthermore only be obtained in a low molecular weight, the high molecular polycarbonates according to the invention, containing s-triazine rings, can surprisingly be obtained in a high molecular weight even if in the general formula la n is equal to I, that is to say if homocondensates containing s-triazine are concerned. Additionally, in contrast to the polycarbonate manufactured according to SU-PS No. 240,233 from the compound 5 and phosgene, the compounds of the invention show very good tough-elastic properties which manifest themselves, for example, in an excellent impact resistance and a good elongation at break.

The copolycarbonates manufactured according to SU-PS No. 240,233 from the compound 5 and 2,2-bis- (4-hydroxyphenyl)-propane show considerable shortcomings in processing by extrusion and injection molding because, firstly, thermal decomposition occurs, with its associated elimination of hydrogen chloride, which causes corrosion of the processing machines and, secondly, undesirable discoloration of the products occurs. These disadvantages do not arise in the new high molecular polycarbonates according to the invention, which contain s-triazine rings. They can be processed without thermal decomposition to give colorless, transparent moldings.

The new high molecular polycarbonates according to the invention, containing s-triazine rings, are obtained by reacting dihalogeno-s-triazines of the formula 6 HaIYNY Hal wherein Hal denotes F, Cl, Br and l, but preferably Cl, and Z and R have the abovementioned meaning with at least two equivalents of an aromatic dihydroxy compound of the formula 7 wherein X has the abovementioned meaning,

in the presence of a compound having a basic reaction, or preferably by reacting the dihalogenostriazines of the formula 6 with the alkali metal salts of the aromatic dihydroxy compounds, according to processes which are in themselves known. The reaction is carried out either a. in an inert organic solvent or b. in an aqueous-alkaline phase or c. in a two-phase mixture of an inert organic solvent and an aqueous-alkaline phase at temperatures between 0 and 300C, preferably between 30 and 150C and using reaction times of between 0.2 and 20 hours, followed by direct reaction of the aromatic dihydroxy compounds, containing s-triazine rings, of the :formula 8, which are formed as intermediates forming derivatives of carbonic acid, such as phosgene and/or the monoand/or bis-chlorocarbonic acid esters of the aromatic dihydroxy compounds, optionally in the presence of chainstoppers, according to known processes for the manufacture of polycarbonates, and preferably according to the interfacial condensation process, g

It is possible to use both different dihalogeno-striazines 6 and also different aromatic bis-hydroxy compounds 7 alongside one another, ifa corresponding carbonate copolymer is desired. Furthermore, it is pos sible, without difficulty, to react the reaction products of dihalogeno-s-triazines with aromatic dihydroxy com pounds with other bis-hydroxy compounds and polycarbonate-forming derivatives of carbonic acid.

The process according to the invention has the ad vantage that the manufacture of the bis-hydroxy compound, containing s-triazine, of the formula8, and the subsequent manufacture of the homopolycarbonates or copolycarbonates, based on 8 and optionally other bishydroxy compounds, can be carried out in the same reaction medium and in the same reaction vessel, without isolation of the intermediate. Separaternanufacture of the bisphenol containing s-triazine, while possible, is

not necessary.

A particular variant for the manufactureof the high molecular polycarbonates according to the invention consists of carrying out the reaction of the dihalogenos-triazine of formula 6 with the bis-hydroxy compound of formula 7 in the presence of 0.01 to 5 mol percent of a trihalogeno-s-triazine, relative to the structural unit of the formula la, with Hal having the meaning indicated for formula 6 but preferably denoting Cl, so

which in the subsequent reaction with polycarbonateforming derivatives of carbonic acid cause a branching of the polycarbonates via s-triazine rings. 1

The dihalogeno-s-triazines used for the manufacture of the homopolycarb onates or copolycarbonates according to the invention, where they are not already known, are manufactured according to the processes known in the chemical literature.

For example, 2-alkylamino-, 2-arylamino-, 2-alkoxy-, 2-aroxy-, 2-alkylthioand Z-arylthio-4,6-dichloro s triazines are obtained by reaction of cyanuric chloride with aliphatic or aromatic amines, alcohols, phenols, mercaptans and thiophenols [see, for example, J. R. Thurston and others, J. Am. Chem. Soc. 73 (1951), pages 2981 and 2990; H. Koopman and others, Rec'. trav. chim. Pays-Bas 78 (1959), page 967].

These and further bisphenols suitable for the manu facture of the high molecular polycarbonates according to the invention are described in US. Pat. Nos. 2,970,131, 2,991,273, 2,999,835, 2,999,846, 3,014,891, 3,028,365, 3,062,781, 3,148,172, 3,271,367, 3,271,368, 3,280,078 and in DT-OS No. 1,570,703.

Suitable molecular weight stoppers are phenol and phenols with one or more substituents, but equally also mono-halogeno-s-triazines of the general formula 9 N. R "IT? Z -R l l N N y Hal in which I Z, R and Hal have the meaning already given above. The manufacture of the homopolycarbonates or copolycarbonates containing s-triazine rings, according to the invention, can be effected, for example, as follows:

The aromatic dihydroxy compound and two equivalents of an alkali hydroxide, preferably sodium hydroxide or potassium hydroxide, are dissolved in sufficient water to give an approximately 10% strength aqueous solution of the alkali metal salt of the bisphenol. Waterinsoluble or sparingly soluble alkali metal salts of dihydroxy compounds are used as an aqueous suspension. It is also possible, without disadvantage, to use more dilute or more concentrated alkali metal salt solutions or suspensions. The desired amount of the dihalogenos-triazine, at most half an equivalent, but at least onehundredth equivalent, relative to the bisphenol, is then added continuously (in portions) or in one portion, as a solution or suspension in a water-immiscible organic solvent which is inert, under the reaction conditions, towards the triazine derivative.

As organic solvents it is possible to use, for example, chlorinated hydrocarbons, such .as CH CI CHCl CCl ethylene chloride and trichloroethylene, ben

zene, toluene, xylenes, chlorobenzene, dichlorobengenes and more highly chlorinated aromatic compounds.

, Sincethe. reaction between the alkali metal salt of the bisphenolandthe dihalogeno-s-triazine takes place principally at the interface between the organic solvent and the water, good mixing must be insured and this canbe done ina manner which is in itself known, for example vigorous stirring. I

- The.we.ll-mixed two-phase mixture is now kept at a temperature between, 0 and 300C, preferably between30 and C, for a period of 0.2 to 20 hours.

As a rule, the condensation is complete after not more than five hours. Theentire reaction up to that point is carried out under an inert gas atmosphere, preferably under nitrogen. The alkali metal salts, of the bisphe n ols, containing s -triaz ine rings, of the formula 8, which are formed, are more or less readily water-soluble depending on'the nature of the dihalogeno-s-triazine used and on the 'nature of the aromatic dihydroxy compound.

in which X, Z, R and Hal have the abovementioned meaning, it is advantageous to choose a large excess of bisphenol and to carry out both the addition of the dihalogeno-striazine and the condensation at elevated temperature. However, the formationof the by-products of the formula 10 does not disturb the total course of the reaction since these compounds arealso smoothly incorporated into the polycarbonate structure.

If desired, a. solvent which is suitable for aromatic polycarbonates, such as methylene chloride, chloroform, carbon tetrachloride and 1,2-dichloroethane, 0r

, chlorinated aromatic compounds, such as dichlorobenzene,-chlorotoluene o r= chlorobenzene, is added to the .two-phase mixture in which possibly the alkali metal salts of the aromatic dihydroxy compound employed in .tween 10 and 14, depending on the nature of the bisphenol components u'sed,=in a manner which is in itself known, with derivatives of carbonic acid which form carbonate groups, such as ,phosgeneor monoand/or bis-chlorocarbonic acid esters. or with precondensates of aromatic dihydroxy "compounds. such as are described in patent specifications.

The hom opolycarbonates or copolycarbonates, con taining s-triazine rings manufactured according to the two-phase boundary process can be isolated in the cus tomary manner, for example by acidifying the reaction mixture which has an alkaline reaction. separating off the aqueous phase washin g' the organic phase with distilled water until it is'free of electrolyte and precipitating'the polycarbonateior distilling off the solvent.

The polymers thus'obtained are low'molecular or high molecular depending on the amount of added chain stopper. i

The new high molecular polycarbonates containing s-triazine rings, according to the invention, are excellent thermoplastics with outstandin'g thermal, electrical and tough-elastic properties. They are distinguished, relative to the commercially available industrial polycarbonates from l2;2-bis-(4-hydroxyphenyl)-propane, by substantially improvedstability to saponification by hot aqueous NaOH solutions, a raised softening point, and improved burning behaviomThus, for example, copolycarbonates based ori 2,2-bis-( 4hydroxyphenyl)- propane and dichloro-s-triazines, such as 2- diphenylamino-4,6 dich1ord-s-triaiine, fromv a content of only 5 percent by we i ght Qfs-triaZine units upwards, meet the "requirements of fire category S E I in the UL- test. The new poly carbonates"according to the invention in general possess glass transition temperatures of above 160C. They fle'ndthemselves very well to processing to givelight colord moldings, sheets and films. They can also be'iisedv'ery readily in mixtures with fillers, for example with. milnerals onc'arbo n black, with substances producings'pecial effects, or with glass fibers, pigments, dyestuffs,j stabilizers and other additives. Theycan, inparticularly be used with great advantage where, in addition: to "great toughness, improved resistance to hydrolysis and better burning behavior are desired or reduired'. Of course, the high molecular polycarbonates containing s-triazine rings, according to the invention,can also be employed in all fields of use where conventional polycarbonates are used. P I

A particular advantage of the polycarbonates according to the invention is that it is'possible to impart certain properties through the -Z R grouping, such as, for example, compatibility-with other polymers, mold release properties, the introduction of polar groups and solubility. I '7 v The invention is'further-illustrated but is not intended to be limited bythe following examples in which all parts and percntagesareby weight unless otherwise specified.

In the e-xamplesthe burning behaviour is determined according UL. Sub. 94 (ver'tica'ltest) with'the ASTM- rod (one-sixteenth inch .onehalf inch. X 5. inch).

The wellstirred mixture is heated for 5 hours under reflux (about 90C). After cooling to room temperature, 300 ml of methylene chloride are added. the pH is adjusted to 13 by adding 22.5 ml of2 N NaOH solution and 29.7 g (0.3 mol) of COC1 are introduced over the course of about 30 minutes at 17 to 21C, with vigorous stirring. During the phosgenation, the pH value is kept constant by dropwise addition of 45% strength NaOH. In total. 15.6 ml of 45% strength NaOH are consumed. After addition of 12 ml of 1% strength aqueous triethylamine solution (0.53 mol per cent relative to bisphenol A) and 4.2 ml of 45% strength NaOH, condensation is continued for a further hour at pH 13.

The organic phase, which contains the polycarbonate containing s-triazine, is separated off, washed twice with dilute phosphoric acid and then with distilled water until free of electrolyte (conductivity l0 0 cm) treated with acetone until it is slightly cloudy and added dropwise to methanol, whereupon the polymer precipitates as a white flocculent material.
